As tax agents at the coal face, we understand private clients, the demands of modern practice and the issues that firms deal with daily. For over 25 years the team at CST has built an international tax practice with offices in Australia, Singapore and the USA. 

'Expand' was founded in 2019 and is dedicated to helping accounting firms who require assistance with international tax issues relevant to their clients - enabling them to focus on what they do best.

We are passionate about helping fellow Australian accountants capitalize on the opportunities, and manage the risks, arising from clients who have international tax issues.
